Sugar Batteries Could Offer 20 Percent More Capacity than Lithium Ion

Lithium-ion batteries have been powering our gadgets for more than 20 years and aren’t going away anytime soon, but serious competition may be emerging in the form of sodium and…sugar. Scientists at the Tokyo University of Science believe that sodium-sucrose-based batteries could deliver a 20% higher energy capacity than today’s lithium-ion batteries.

Sodium-Sucrose Batteries May Be Cheaper And Longer-Lasting

As it turns out, heat-blasted sugar can convert to carbon powder, which can add storage capacity to a sodium-ion battery. Lithium can be found in several locations around the world (including Argentina and China), but major deposits are few. Sodium, on the other hand, is easy to come by and inexpensive. So, conceivably, sodium-sucrose batteries may not only have longer battery life, but be less expensive, as well.

Sodium-sucrose batteries are still a long way off from hitting the market. The team that made the discovery predicts at least five years before the real sodium-sucrose batteries find consumers – and that’s if a major hurdle is overcome: as it stands now, these batteries would likely have fewer charge cycles than lithium-ion batteries.
